With the continuous improvement of the economic level,people gradually favor the ride stability and handling stability of the vehicle.Compared with the traditional passive suspension,the electronically controlled air suspension is loved by people because of its unique way of vibration reduction.The air suspension can adapt to the road and conditions to adjust to the best damping performance,and at the same time improve the car attitude to improve the handling stability.The paper analyzes the dynamics of the electronically controlled air suspension of the vehicle,and focuses on the influence of the electronically controlled air suspension on the state performance of the vehicle based on the electric vehicle,and controls the control strategy of the electronically controlled air suspension reasonably and effectively.Body pitch angle,center of mass vibration acceleration,etc.improve vehicle ride comfort.The main research contents of the paper are as follows:First,research and analysis of the development status of electronically controlled air suspension technology at home and abroad,and in-depth analysis of the structure and performance characteristics of electronically controlled air suspension,based on its dynamic analysis,using MATLAB/SUMULINK software builds a ten-degree-offreedom vehicle model.The model includes electronically controlled air suspension,air springs,road surface input,tire section and auxiliary calculations,and vehicle dynamics.(2)The research and analysis of the dynamics of the vehicle's electronically controlled air suspension system explores the effects of different control algorithms on the vertical kinematics of the electronically controlled air suspension vehicle and the attitude of the vehicle at different speeds and road conditions.An electronically controlled air suspension control system based on crowd algorithm is proposed,and an adaptive PID controller is designed based on the roll pitch angle and vibration acceleration of the vehicle as output variables.(3)Simulation verification of the vehicle electronically controlled air suspension control system under typical operating conditions,for further verification of its control system,implementation of an electronically controlled air suspension hardware-in-theloop test platform,and the use of Anhui Agricultural University The Institute's selfmade test vehicle carries out the hardware-in-the-loop test to verify the vehicle model and control system structure.The results show that this control system can effectively improve the vertical performance and attitude of the vehicle and significantly improve the ride comfort of the vehicle.
